Management of traumatic lung injury: a Western Trauma Association Multicenter review.

BACKGROUND: Improved outcomes following lung injury have been reported using "lung sparing" techniques. METHODS: A retrospective multicenter 4-year review of patients who underwent lung resection following injury was performed. Resections were categorized as "minor" (suture, wedge resection, tractotomy) or "major" (lobectomy or pneumonectomy). Injury severity, Abbreviated Injury Scale (AIS) score, and outcome were recorded. RESULTS: One hundred forty-three patients (28 blunt, 115 penetrating) underwent lung resection after sustaining an injury. Minor resections were used in 75% of cases, in patients with less severe thoracic injury (chest AIS scores "minor" 3.8 +/- 0.9 vs. "major" 4.3 +/- 0.7, p = 0.02). Mortality increased with each step of increasing complexity of the surgical technique (RR, 1.8; CI, 1.4-2.2): suture alone, 9% mortality; tractotomy, 13%; wedge resection, 30%; lobectomy, 43%; and pneumonectomy, 50%. Regression analysis demonstrated that blunt mechanism, lower blood pressure at thoracotomy, and increasing amount of the lung resection were each independently associated with mortality. CONCLUSION: Blunt traumatic lung injury has higher mortality primarily due to associated extrathoracic injuries. Major resections are required more commonly than previously reported. While "minor" resections, if feasible, are associated with improved outcome, trauma surgeons should be facile in a wide range of technical procedures for the management of lung injuries.     

Lung-sparing techniques are associated with improved outcome compared with anatomic resection for severe lung injuries

BACKGROUND: Pulmonary tractotomy was introduced in 1994 as a novel concept for lung salvage after penetrating wounds. Recently, tractotomy has been suggested to increase morbidity and, thus, its practice has been challenged. The purpose of this study was to compare the morbidity and mortality associated with nonanatomic and anatomic lung resection in the management of severe pulmonary injuries. METHODS: Using our trauma registry, patients admitted to an urban Level I trauma center during an 11-year period with thoracic injuries requiring thoracotomy and pulmonary operation were identified. A chart review was performed with attention to patient demographics, operative treatment, and outcome. Pulmonary operations performed were classified as either nonanatomic (wedge resection and tractotomy) or anatomic resection (lobectomy and pneumonectomy). Statistical analysis was performed using Student's test, Fisher's exact test, and logistic regression as appropriate. RESULTS: There were 34 men and 2 women, with a mean age of 29 +/- 2 years. Mechanism of injury was predominantly penetrating, with 26 (72%) gunshot wounds and 8 (22%) stab wounds. Intraoperative blood loss and early red blood cell transfusion requirement were lower in patients undergoing nonanatomic resection (3.85 L vs. 11.90 L and 17.4 U vs. 27.9 U, respectively; p < 0.05). Mortality was 4% in the nonanatomic resection group versus 77% in the anatomic resection group. CONCLUSION: Nonanatomic resection is associated with an improved morbidity and mortality compared with anatomic resection in the management of severe lung injuries. Although not a randomized study, these findings encourage the continued application of lung-sparing procedures when feasible.     

Surgical management of traumatic pulmonary injury

BACKGROUND: Surgical treatment of traumatic pulmonary injuries requires knowledge of multiple approaches and operative interventions. We present a 15year experience in treatment of traumatic pulmonary injuries. We hypothesize that increased extent of lung resection correlates with higher mortality. METHODS: Surgical registry data of a level 1 trauma center was retrospectively reviewed from 1984 to 1999 for traumatic lung injuries requiring operative intervention. Epidemiologic, operative, and hospital mortality data were obtained. RESULTS: Operative intervention for traumatic pulmonary injuries was required in 397 patients, of whom 352 (89%) were men. Penetrating trauma was seen in 371 (93%) patients. Location of the injuries was noted in the left side of the chest in 197 (50%), right side of the chest in 171 (43%), and bilateral in 29 (7%). Operative interventions included pneumonorraphy (58%), wedge resection or lobectomy in (21%), tractotomy (11%), pneumonectomy (8%), and evacuation of hematoma (2%). Overall mortality was 27%. If concomitant laparotomy was required, mortality increased to 33%. The mortality rate in the pneumonectomy group was 69.7%. CONCLUSIONS: The majority of lung injuries occurred in males due to penetrating trauma. Surgical treatment options ranged from simple oversewing of bleeding injury to rapid pneumonectomy. Mortality increased as the complexity of the operative intervention increased. Rapid intraoperative assessment and appropriate control of the injury is critical to the successful management of traumatic lung injury.     

Pulmonary Resection for Lung Trauma

Background. Pulmonary resection is rarely required for trauma, and its mortality is reportedly high.

Methods. A 10-year retrospective review of pulmonary resections for trauma was done.

Results. Of 2,455 patients with chest trauma, 183 (7.4%) underwent thoracotomy and 32 (1.3%) required pulmonary resection. Mean age was 28.4 years and mean injury severity score was 24.5. Mechanism of injury was stab wound in 14 patients, gunshot wound in 6, and blunt trauma in 12. Blunt trauma patients had a higher injury severity score (29.6) than penetrating trauma patients (21.4), but this was not significant (p < 0.07). Indications for thoracotomy were hemorrhage in 24 patients, airway disruption in 4, and other indications in 4. Operations consisted of wedge resection (19 patients), lobectomy (9), and pneumonectomy (4). Four (12.5%) patients (pneumonectomy, 2; lobectomy, 1; wedge, 1) died. Mortality for pneumonectomy was 50%, but this was not significantly higher than for lesser resections. Blunt trauma had a higher mortality (33%) than penetrating trauma (0%) (p < 0.02). Nonsurvivors had higher injury severity scores (44.2) than survivors (21.6) (p < 0.001).

Conclusions. Pulmonary resection is infrequently required for lung injury. Overall mortality is lower than previously reported, but pneumonectomy has a high mortality. Blunt trauma has a higher mortality than penetrating trauma. Injury severity scores are higher for nonsurvivors than survivors; this shows the importance of associated injuries on outcome.     

Subsequent pulmonary resection for bronchogenic carcinoma after pneumonectomy

BACKGROUND: Patients who have undergone a pneumonectomy for bronchogenic carcinoma are at risk of cancer in the contralateral lung. Little information exists regarding the outcome of subsequent lung operation for lung cancer after pneumonectomy. METHODS: The records of all patients who underwent lung resection after pneumonectomy for lung cancer from January 1980 through July 2001 were reviewed. RESULTS: There were 24 patients (18 men and 6 women). Median age was 64 years (range, 43 to 84 years). Median preoperative forced expiratory volume in 1 second was 1.47 L (range, 0.66 to 2.55 L). Subsequent pulmonary resection was performed 2 to 213 months after pneumonectomy (median, 23 months). Wedge excision was performed in 20 patients, segmentectomy in 3, and lobectomy in 1. Diagnosis was a metachronous lung cancer in 14 patients and metastatic lung cancer in 10. Complications occurred in 11 patients (44.0%), and 2 died (operative mortality, 8.3%). Median hospitalization was 7 days (range, 2 to 72 days). Follow-up was complete in all patients and ranged between 6 and 140 months (median, 37 months). Overall 1-, 3-, and 5-year survivals were 87%, 61%, and 40%, respectively. Five-year survival of patients undergoing resection for a metachronous lung cancer (50%) was better than the survival of patients who underwent resection for metastatic cancer (14%; p = 0.14). Five-year survival after a solitary wedge excision was 46% compared with 25% after a more extensive resection (p = 0.54). CONCLUSIONS: Limited pulmonary resection of the contralateral lung after pneumonectomy is associated with acceptable morbidity and mortality. Long-term survival is possible, especially in patients with a metachronous cancer. Solitary wedge excision is the treatment of choice.     

Surgical treatment for bilateral multiple lung cancers]

We reviewed 21 patients with bilateral multiple bronchogenic carcinomas. Eleven of them had synchronous carcinomas and 10 had metachronous carcinomas. We treated 6 patients with lobectomy and wedge resection under median sternotomy synchronously, and 2 patients with lobectomy on both lungs under standard thoracotomy, 2 patients with lobectomy and wedge resection, 1 patient with segmentectomy on both lung, 1 patient with lobectomy and segmentectomy, 1 patient with pneumonectomy and wedge resection, and 8 patients with lobectomy and thoracoscopic wedge resection on each lung metachronously. Two patients who had lobectomy on both lungs were dead, one of whom of pulmonary edema 2 weeks after second operation and the other of respiratory failure 3 years after second operation. We concluded that lobectomy on both lungs are not recommended because of high mortality rate (10%) and the limited resection under thoracoscopic surgery should be considered to treat the other contra lateral primary lung cancers.     

Multiple primary lung cancers. Results of surgical treatment

During a 13-year period, multiple primary lung cancers were diagnosed in 80 consecutive patients. Forty-four patients had metachronous cancers. The initial pulmonary resection was lobectomy in 36 patients, bilobectomy in 3, pneumonectomy in 1, and wedge excision or segmentectomy in 4. The second pulmonary resection was lobectomy in 16 patients, bilobectomy in 2, completion pneumonectomy in 7, and wedge excision or segmentectomy in 19. There were two 30-day operative deaths (mortality rate, 4.5%). Actuarial 5- and 10-year survival rates after the first pulmonary resection for stage I disease were 55.2% and 27.0%, respectively. Five-year and 10-year survival rates for stage I disease after the second pulmonary resection were 41.0% and 31.5%, respectively. The remaining 36 patients had synchronous cancers. The pulmonary resection was lobectomy in 18 patients, bilobectomy in 3, pneumonectomy in 10, and wedge excision or segmentectomy in 8. There were two 30-day operative deaths (mortality rate, 5.6%). Actuarial overall 5- and 10-year survival rates after pulmonary resection were 15.7% and 13.8%, respectively. We conclude that an aggressive surgical approach is safe and warranted in most patients with multiple primary lung cancers and that the presence of synchronous primary cancers is ominous.     

Morbidity and mortality after neoadjuvant therapy for lung cancer: the risks of right pneumonectomy

BACKGROUND: The risks of complications in patients undergoing thoracotomy after neoadjuvant therapy for nonsmall cell lung cancer remain controversial. We reviewed our experience to define it further. METHODS: All patients undergoing thoracotomy after induction chemotherapy from 1993 through 1999 were reviewed. Univariate and multivariate methods for logistic regression model were used to identify predictors of adverse events. RESULTS: Induction chemotherapy included mitomycin, vinblastine, and cisplatin (179 patients), carboplatin and paclitaxel (152 patients), and other combinations (139 patients). Eighty-five patients (18%) received preoperative radiation. Operations were pneumonectomy (97 patients), lobectomy (297 patients), lesser resection (18 patients), and exploration only (58 patients). Total mortality was 7 of 297 (2.4%) and 11 of 97 (11.3%) for all lobectomies and pneumonectomies, respectively, but mortality was 11 of 46 (23.9%) for right pneumonectomy. Complications developed in 179 patients (38%). By multiple regression analysis, right pneumonectomy (p = 0.02), blood loss (p = 0.01), and forced expiratory volume in one second (percent predicted) (p = 0.01) predicted complications. No factor emerged to explain this high right pneumonectomy mortality rate. CONCLUSIONS: Pulmonary resection after neoadjuvant therapy is associated with acceptable overall morbidity and mortality. However, right pneumonectomy is associated with a significantly increased risk and should be performed only in selected patients.     

Bronchoplastic surgery for lung cancer and the results

Fifty-nine patients with lung cancer underwent bronchoplastic surgery in our institute from September, 1965 to May, 1982. The post surgical stages of disease were as follows: 7 cases of Stage I disease, 7 cases of Stage II, 41 cases of Stage III, 4 cases of Stage IV. The bronchoplastic surgery performed included sleeve resection combined with lobectomy in 35, wedge resection combined with lobectomy in 11, reconstruction of the lower area of the trachea in 5, bronchial sleeve resection combined with pulmonary artery resection in 6 and bronchial wedge resection combined with pulmonary artery resection in 2. There was no case of operative mortality within 30 days after the operation. To prevent postoperative complications, careful techniques are required in suturing and postoperative bronchoscopic suction of intrabronchial secretion is necessary. The use of Dexon or Dexon S, polyglycolic acid sutures, showed good results. Adjuvant therapies were performed on 42 cases, including preoperative infusion of Mitomycin C into the bronchial arteries or postoperative irradiation or both. Twenty-eight of 59 were alive and well from 7 months to 16 years after the operations. The relative 5 year survival rates were 40.5 per cent in total cases and 46.5 per cent in those with squamous cell carcinomas. The prognosis of patients undergoing bronchoplasty was compared with that of patients undergoing lobectomy and pneumonectomy. There was a statistical difference between bronchoplasty and pneumonectomy.     

Iterative surgical resections for local recurrent and second primary bronchogenic carcinoma.

OBJECTIVE: To report our experience with repeated pulmonary resection in patients with local recurrent and second primary bronchogenic carcinoma, to assess operative mortality and late outcome. METHODS: The medical records of all patients who underwent a second lung resection for local recurrent and second primary bronchogenic carcinoma from 1978 through 1998 were reviewed. RESULTS: There were 27 patients. They constituted 2.5% of 1059 patients who had undergone lung resection for bronchogenic carcinoma in the same period. Twelve patients (1.1%) (group 1) had a local recurrence that developed at a median interval of 24 months (range 4-83).The first pulmonary resection was lobectomy in ten patients and segmentectomy in two. The second operation consisted of completion pneumonectomy in ten cases, completion lobectomy in one and wedge resection of the right lower lobe after a right upper lobectomy in one. The other 15 patients (1.4%) (group 2) had a new primary lung cancer that developed at a median interval of 45 months (range 21-188).The first pulmonary resection was lobectomy in 12 patients, bilobectomy in one and pneumonectomy in two. The second pulmonary resection was controlateral lobectomy in seven patients, controlateral sleeve lobectomy in two, controlateral pneumonectomy in 1, controlateral wedge resection in four and completion pneumonectomy in one. Overall hospital mortality was 7.4%, including one intraoperative and one postoperative death in group 1 and 2, respectively. Five-year survival after the second operation was 15.5 and 43% with a median survival of 26 and 49 months in groups 1 and 2, respectively (P=ns). CONCLUSIONS: Long-term results justify complete work-up of patients with local recurrent and second primary bronchogenic carcinoma. Treatment should be surgical, if there is no evidence of distant metastasis and the patients are in good health. Early detection of second lesions is possible with an aggressive follow-up conducted maximally at 4 months intervals for the first 2 years and 6 months intervals thereafter throughout life.     

Survival after bronchoplastic lobectomy for non small cell lung cancer compared with pneumonectomy according to nodal status.

BACKGROUND: In this retrospective study we have compared the results after sleeve lobectomy and pneumonectomy performed for non small cell lung cancer in the period January 1990-December 1995 at the Thoracic Surgery Unit, University Hospital of Siena. Follow-up was updated until December 2000. METHODS: In that period, 38 patients underwent sleeve lobectomy and 127 underwent pneumonectomy. The bronchoplasty was a full sleeve in 30 patients and a bronchial wedge resection in eight. Systemic nodal dissection was undertaken routinely. RESULTS: The 30-day postoperative mortality was 5.2% (2/38) in the sleeve lobectomy group and 3.9% (5/127) in the pneumonectomy group. Postoperative complications occurred in 23.6% of patients in the sleeve lobectomy group and in 23.2% of those in the pneumonectomy group. Local recurrences occurred in 5.2% of patients in the sleeve lobectomy group and in 4.8% of those in the pneumonectomy group. The overall 5-year survival for the sleeve lobectomy group was 38% whereas that for the pneumonectomy group was 25% (p=0.03). Regarding lymph-node involvement, in the sleeve lobectomy group, the 5-year survival for N0, N1 and N2 was 62.5, 17.5 and 12.5%, respectively. CONCLUSIONS: Our data confirm that sleeve lobectomy, when performed in selected patients with non small cell lung cancer, provides at least similar overall long term survival to that seen after pneumonectomy. Long term result are chiefly related to nodal stage with a significantly lower survival for patients with nodal involvement. As most patients with nodal involvement die from distant metastases, adjuvant treatment, instead of type of resection, would play a major role in prolonging survival.     

Favorable results after sleeve lobectomy or bronchoplasty for bronchial malignancies

Background. Sleeve lobectomy and bronchoplasty are established alternatives to pneumonectomy for bronchial malignancies involving a main bronchus. However, potential bronchial anastomotic complications have deterred the general application of these types of resection. Some reports have contained a mixture of non-small cell lung cancer (NSCLC) and tumors of low-grade malignancy, making it difficult to assess the long-term results of these procedures as an alternative to pneumonectomy for lung cancer.

Methods. We retrospectively reviewed our experience with sleeve lobectomy and bronchoplasty for bronchial malignancies from January 1988 to September 1998 separating NSCLC (n = 58) from tumors of low-grade malignancy (n = 19). We compared the overall results between sleeve lobectomy and pneumonectomy (n = 142) performed for NSCLC over the same time interval.

Results. For NSCLC, after sleeve lobectomy, the operative mortality was 5.2% (3 of 58 patients) and the overall 5-year actuarial survival was 37.5%. After pneumonectomy, the operative mortality was 4.9% (7 of 142 patients) and the overall 5-year actuarial survival was 35.8%. For tumors with low-grade malignancy, there was no operative mortality after sleeve lobectomy or bronchoplasty and the 5-year actuarial survival was 100%. Major bronchial anastomotic complications occurred in 3 patients among the 77 patients who underwent sleeve resection.

Conclusions. Sleeve resection can be performed with a low risk of bronchial anastomotic complication. The long-term survival after sleeve resection for NSCLC is similar to pneumonectomy. Excellent results are obtained after sleeve resection for low-grade malignancies.     

Supraventricular arrhythmias after resection surgery of the lung.

OBJECTIVE: Two hundred consecutive patients undergoing resection surgery of the lung during 1999 were retrospectively reviewed to define prevalence, type, clinical course and risk factors for postoperative supraventricular arrhythmias (SVA) with particular reference to atrial fibrillation or flutter (AF). METHODS: Records of 200 lung patients were collected and analysed with particular attention to preoperative physiologic values and associated pathologies, lung functional status, electrocardiogram registration, extent of surgical resection of the lung and were also analysed to confirm or exclude correlation between them and postoperative AF; three patients were excluded as they were affected preoperatively by SVA. RESULTS: Forty-five episodes of SVA, 41 of AF were identified in 197 patients (22%) and were more prevalent in several groups of patients such as those with increased age, pneumonectomy and superior lobectomy. Rhythm disturbances were most likely to develop on the second day after surgery. Ninety-eight percent of AF disappeared within a day of discharge and sinus rhythm was restored with digitalis or other antiarrhythmic drugs in all patients except one who was discharged with persistent atrial fibrillation. Arrhythmias were not direct causes of any in-hospital deaths. There is a tendency in the difference of the AF rate between pneumonectomy and upper lobectomy patients versus inferior lobectomy ones, probably related to the different anatomic structure of the proximal trunks of the upper and inferior veins of the lung, respectively. CONCLUSIONS: Statistical analysis revealed that increased age, extent and type of pulmonary resection, such as pneumonectomy and superior lobectomy were significant risk factors. Despite these factors, arrhythmias after lung surgery could be managed easily and were not closely related to higher mortality. Direct cause of AF after lung resection surgery remains unclear; anatomical substrate such as surgical damage to the cardiac plexus or to the proximal trunks of the pulmonary veins covered by myocardial sleeves with electrical properties are to be considered.     

Can pneumonectomy for non-small cell lung cancer be avoided? An audit of parenchymal sparing lung surgery.

BACKGROUND: Lung cancer resection rates are suboptimal in the UK. Pneumonectomy has a higher perioperative mortality risk than lobectomy. To increase resection rates and improve outcomes we have implemented a policy of parenchymal sparing surgery for tumours involving a main stem bronchus. METHODS: In a prospective 4 year study of 119 consecutive patients operated upon by a single surgeon the perioperative course, pathology and survival were compared for 81 patients undergoing pneumonectomy and 38 patients in whom pneumonectomy was avoided by bronchoplastic+/-angioplastic procedures. RESULTS: The rate of pneumonectomy decreased significantly with increasing experience with parenchymal sparing surgery (R(2)=0.98, P<0.001) with 21 of the last 30 patients (70%) avoiding pneumonectomy. There were no significant inter-group differences in patient characteristics, perioperative course or outcome. One-year survival was 64% after pneumonectomy and 73% after sleeve lobectomy. However the perioperative loss of respiratory function was significantly lower in the patients in whom pneumonectomy was avoided (P=0.0003). CONCLUSIONS: Pneumonectomy can be avoided in a large proportion of patients with non-small cell lung cancer of a main stem bronchus without adversely affecting outcome but with preservation of lung function     

Pulmonary resection after pneumonectomy

Patients who have a lung cancer in the residual lung after pneumonectomy should not be automatically excluded for surgical consideration. These patients should be carefully staged and evaluated physiologically. The most important initial differentiation is to distinguish a true second primary lung cancer from metastatic recurrent lung cancer. Meticulous staging with chest CT, PET, brain MRI, and mediastinoscopy should be able to successfully exclude metastatic disease, multifocal disease, or locally advanced tumors. Only patients who have stage I disease are candidates for this type of extended resection. Ideally, these patients should have small peripheral tumors that can be encompassed with a low-volume wedge resection. More extended resections, such as segmentectomy or right middle lobectomy, may be considered in some patients but seem to bear a higher operative morbidity and mortality. The need for an upper or lower lobectomy after contralateral pneumonectomy is probably an absolute contraindication to surgical resection. To tolerate pulmonary resection after pneumonectomy, and to obtain the desired survival benefit, patients should have a good to excellent performance status, no serious comorbidities, and a ppoFEV1 greater than 1.0 L/second. In these highly selected patients, pulmonary resection after pneumonectomy can be accomplished with an acceptable operative morbidity and mortality and, in true cases of metachronous second primary lung cancers, may achieve a 5-year survival rate of up to 50%.

Abstract：

Objective To verify the outcome and long-term survival of surgical management for double primary lung cancers. Methods The clinical data of 98 patients with double primary lung cancers admitted between January 1999 and June 2009 was analyzed retrospectively. There were 72 cases of synchronous double primary lung cancers, including 54 males and 18 females with median age of onset of 66 years (37 to 79 years). Thoracic surgical procedures for 144 tumor lesions included lobectomy for 9 cases, bilobectomy for 14 cases, pneumonectomy for 6 cases, lobectomy plus wedge resection for 33 cases, double wedge resection for 9 cases, and bilobectomy plus wedge resection for 1 case. There were 26 cases of metachronous double primary lung cancers, including 20 males and 6 females. The median age for the first primary cancer was 59. 5 years (38 to 73 years) , for second primary cancer was 66 years (47 to 77 years). Thoracic surgical procedures for 52 tumor lesions included lobectomy for 31 cases, bilobectomy for 1 cases, wedge resection for 10 cases, and pneumonectomy for 8 cases. Results The overall 30-day mortality was 0.Postoperative complications rate was 13. 3% . All patients were followed up after the operation. Until December 2009, follow-up rate was over 90%. Five-year survival for all the patients from the time of initial diagnosis of cancer was 66. 4%. Five-year survival for patients with metachronous and synchronous disease from the time of initial diagnosis of cancer was 96. 2% and 43. 0% ( P =0. 000) , respectively. Survival at 5 years for the second cancer of metachronous disease and synchronous disease was 45. 9% and 43. 0% (P =0. 634) ,respectively. Conclusion Surgical treatment for double primary lung cancer is reasonable, and the patients can make long-term survival.     

Management of penetrating lung injuries in civilian practice

Recent reports of military thoracic injuries have advocated early thoracotomy and aggressive management of pulmonary injuries with resection as opposed to the more conservative and traditional treatment with chest tube thoracostomy. A retrospective study was therefore performed to determine the incidence of thoracotomy and lung resection in civilian injuries and to evaluate the effectiveness of treatment of these injuries. Between 1973 and 1985, in a series of 1,168 patients, there were 384 gunshot wounds and 784 stab wounds to the thorax. Two hundred eighty-three patients with a gunshot wound (74%) and 602 with a stab wound (77%) were treated with chest tubes alone. Sixty-eight patients (6% of the total) required operative repair of pulmonary hilar or parenchymal injury. Pulmonary resection was necessary in only 18 patients (nine with a gunshot wound and nine with a stab wound), and 10 patients had repair of hilar injuries (nine with a gunshot wound and one with a stab wound). Of patients requiring pulmonary resection, nine required wedge or segmental resection, six required lobectomy, and three patients required pneumonectomy. Mortality for all thoracic injuries was 2.3%: for those treated with chest tube alone, 0.7%; for pulmonary hilar injuries, 30%; for pulmonary parenchymal injuries, 8.6%; and for injuries necessitating lung resection, 28%. Most civilian lung injuries can be treated by tube thoracostomy alone. Although relatively few patients with primary pulmonary injury require thoracotomy, those that do are at significant risk and may require lung resection to control bleeding or hemoptysis or to remove destroyed or devitalized lung tissue.
